This study aims to develop a scale on the use of self-regulated L2 learning strategies based on Oxford's (2011) Strategic Self-Regulation ((SR)-R-2) Model. The study was conducted with 305 (232 female, 73 male) participants. In order to determine construct validity, EFA and CFA were applied. Depending on the results of EFA, the scale is composed of 35 items on a 4 point Likert type embedded in 6 dimensions (the total variance explained is 41.625%, factor loadings of 35 items vary from .80 to .35.). CFA confirmed the results of EFA, and the findings showed that the model had acceptable fit (chi 2/df=1298.61/545). The corrected item total correlation values of items in the scale range from .44 to .76. The results of t-test with top 27% and bottom 27% groups revealed that the differences are significant (p<.05) for all items and factors. The overall reliability of the model demonstrated that the model is acceptable with a Cronbach's alpha statistic of 0.85. The findings reveal that the scale is a valid and reliable instrument which can be used to identify L2 learners' strategy preferences and to what extent they use them in language education contexts.
